Cleaning up, and found something relevant here: anyone want a memento - I have an original RH 5.2 set. No, not RHEL, I said RH 5.2 mark

Troubles expanding file system.
by Jeff Boyce 01 Sep '21

01 Sep '21

Greetings - I have tried posting this four times now, from two different email addresses (on the 25th, 27th, 30th, and 31st) and it never appeared. I don't see it in the archives, so it appears to be getting dropped in transition for some reason. I am not getting messages from the email system saying it is undeliverable, or is bounced; I am sending as plain text, not HTML, I stripped off my signature. If this makes it through, someone please give me a clue why the others might not have. But that is not as important as the real issue that I am trying to get addressed below. Thanks for any assistance. I have a Dell PowerEdge server with a CentOS KVM host (Earth) with one CentOS guest (Sequoia) that I am trying to expand the partition and filesystem on. I have LVM logical volumes on the host system (Earth), which are used as devices/partitions on the guest system (Sequoia). In this particular situation I have successfully extended the logical volume (lv_SeqEco) on Earth from 500GB to 700GB. 1. Checking the disk information (lsblk) on Earth shows that the logical volume (lv_SeqEco) is now listed as 700GB. 2. Checking disk information (lsblk) on Sequoia shows that the disk /dev/vde is still listed as 500GB, and partition /dev/vde1 where the mount point /ecosystem is located is also listed as 500GB. 3. I had tried using the resize2fs command to expand the filesystem on /dev/vde1, but it returned with the result that there was nothing to do. Which makes sense now after I checked the disk information, since /dev/vde on Sequoia has not increased from 500GB to 700GB. 4. On previous occasions when I have done this task, I would just start GParted on Sequoia and use the GUI to expand the partition and filesystem. A real quick and simple solution. 5. The problem I have now is that the VGA adapter on my server has died and I have no graphical output to the attached monitor, nor to the iDrac console display. So I am stuck doing this entirely by the command line while logged into the system remotely. 6. I suspect that I need to rescan the devices on Sequoia so that it recognizes the increased space that has been allocated from the extended the logical volume. But when I did that (command below) it came back with a no such file or directory. echo 1 > /sys/class/block/vde1/device/rescan 7. This server is being retired in the next few months, but I need this additional space prior to migrating to the new system. Can someone give me some guidance on what I am missing in this sequence? Let me know if I haven't been clear enough in the explanation of my systems and objective. Thanks. Jeff

systemd | Requires statement with an instantiated service
by Leon Fauster 01 Sep '21

01 Sep '21

Maybe the work day is already to long. I can not find a solution for following requirement. How to apply a "Requires" with an instantiated service. Example: a@.service b.service a@.service is started as a(a)host1.service and b.service must be started after a(a)host1.service but the unit will be differently parameterized (depended of the region). So I want to generalize the requires statement. My dropin file in ./b.service.d/dep.conf looks like [Unit] Requires="a(a)*.service" This just produces following error: 'Failed to add dependency on "a(a)*.service", ignoring: Invalid argument' I use also a Before=b.service statement for a@.service but that is not enough. Any hints? -- Thanks, Leon

Re: [CentOS] Application migration
by Mark Woolfson 01 Sep '21

01 Sep '21

Hello, I have some data analysis applications running on CentOS 6.4 and 6.6. Due to these CentOS variants not being supported on the Intel Ice Lake server platform I have to migrate them. The minimum CentOS variant which works on the Ice Lake is 7.4. Please can you give me an idea of the migration complexity of moving the applications from 6.4/6.6 to 7.4 or any variant of 7.

Upgrading (?) from legacy boot to UEFI
by Rob Kampen 30 Aug '21

30 Aug '21

After three days of effort I have failed to find a way of shifting a server from legacy boot to UEFI boot. I have made my way through the 400+ pages of RH installation manual for EL7, plus their similarly large system administrators manual. Dozens of pages searched via google and yet none of the layouts for the /boot and /boot/efi have worked in my case. System is a Lenovo 3650 M5 with UEFI bios. Due to RH / CentOS design my initial install onto the two 600GB HDD partitioned these using MBR and legacy boot. I have just obtained two SAS SSD drives of 3.8TB and thus MBR is no longer an option. I have successfully migrated all the system and data from the HDD to the SSD, complete with GPT and RAID1 and all works as expected - except the HDD was still needed to boot the system. That's when the fun / agony started. Each system reboot is almost five minutes just to get to the <F1> for system setup option. Thus testing is a very slow process. I am now at the point where I have a "bios boot" partition (1024K type ef02) as the first partition on each GPT partitioned SSD and have grub2-install onto the drives the bios boot junk needed for legacy boot. Thus I can at least legacy boot from one of the SSD and all comes up as expected. (no idea yet why it only works from one of the SSD and not the other). Unfortunately the server is remote and the CentOS7 USB device I left plugged into the machine refuses to boot from UEFI mode. Thus a rescue mode boot has not been possible. I have two 300MB partitions, one on each SSD suitably formatted (type ef00 and vfat) and set up with the files as follows: -rwx------. 1 root root 134 Aug 1 2020 BOOT.CSV -rwx------. 1 root root 134 Aug 1 2020 BOOTX64.CSV drwx------. 2 root root 4096 Aug 27 16:22 fonts -rwx------. 1 root root 6597 Aug 27 21:33 grub.cfg -rwx------. 1 root root 1024 Aug 26 23:22 grubenv -rwx------. 1 root root 1122120 Mar 17 07:24 grubx64.efi -rwx------. 1 root root 19378672 Aug 26 20:29 initramfs-3.10.0-1160.36.2.el7.x86_64.img -rwx------. 1 root root 1154640 Aug 1 2020 mmx64.efi -rwx------. 1 root root 1154640 Aug 1 2020 MokManager.efi -rwx------. 1 root root 1243864 Aug 1 2020 shim.efi -rwx------. 1 root root 1237824 Aug 1 2020 shimx64-centos.efi -rwx------. 1 root root 1243864 Aug 1 2020 shimx64.efi -rwx------. 1 root root 6777448 Aug 26 20:27 vmlinuz-3.10.0-1160.36.2.el7.x86_64.efi unfortunately grub2-mkconfig sets up the grub.cfg as for legacy boot because the /sys/firmware/efi does not exist, thanks to running from a legacy boot. I tried a few manual edits to the grub.cfg to deal with linux16 -> linuxefi and initrd16 -> initrdefi but to little avail. Can someone point me to what needs to happen for UEFI boot to work successfully. I am unsure what file I need to point the UEFI bios disk manager setup at, I have tried shim.efi and shimx84-centos.efi The message I get is that linux16 and initrd16 cannot find their files. The change to linuxefi and initrdefi also fail but the system reboot happens before I can see what flashes on screen. Is a USB based UEFI booted rescue mode the only way I can fix this? TIA for your pointers / suggestions.

Annoying shortcut
by mark 27 Aug '21

27 Aug '21

For at least this year, I'm finding that whether I'm in LibreOffice, or Thunderbird, or Firefox, if I do *something*, and I haven't identified what, backspace will delete the entire word, though I haven't hit ctrl-bkspc. In system settings, it should only be the ctrl-bkspc. Has anyone else seen this behavior? mark

Hi, If I enable Secure Boot in my UEFI I get this error (just after selecting Centos from the grub menu) grub-core/kern/efi/sb.c:151: bad shim signature grub-core/loader/i386/efi/linux.c:208: you need to load the kernel first Can someone explain to me why I get this, please? And what can I do to get Centos to boot with Secure Boot? My system: NAME="CentOS Linux" VERSION="8" CentOS Linux release 8.4.2105 Thank you.
